Hi guys, I was just driving home pulling out of a junction and all of a sudden I hear a misfire then the car stalls. So I pull over and restart the car and it starts idling up and down, I turn it back off and leave it for 5 then restart it and it’s idling fine but when I start driving away it won’t build up speed quickly and you can hear the turbo spooling really loudly but it won’t go into boost. I’ve checked the hoses around the turbo but I’m not sure if it has something to do with the PCV or DV valve, I also seen some one mention something about the turbo actuator rod snapping.

Any help would be much appreciated

Check for codes, could be the diverted valve stuck open but just hasn’t thrown up a light yet, also I’m pretty sure they are electronically controlled actuators on the turbos but don’t quote me on that

It wont be the DV stuck open, that wouldn't make the car stall or cut out

Does sound like an air leak though. PCV is an easy check, takes a few minutes, otherwise you'll need to be checking your pipework, particularly the bayonet/push fitting to the intercooler

Actuator rod wouldn't cause your symptoms either so forget that
